<a class="link" href="AtkComponent.html" title="AtkComponent"><span class="type">AtkComponent</span></a> should be implemented by most if not all UI elements with
an actual on-screen presence, i.e. components which can be said to have
a screen-coordinate bounding box.  Virtually all widgets will need to

<a class="link" href="AtkObject.html" title="AtkObject"><span class="type">AtkObject</span></a> class.  In short, only UI elements which are *not* GUI
elements will omit this ATK interface.

A possible exception might be textual information with a transparent

provided by <a class="link" href="AtkText.html" title="AtkText"><span class="type">AtkText</span></a>.
